Furthermore, it is off US 2006/0151986 A1 a vehicle trailer known, which is designed as a crash cushioning device. Upon impact of a vehicle at the rear of the vehicle trailer rods of the vehicle trailer, which are arranged longitudinally in the direction of travel, cut open. The kinetic energy is thus expended in an energy for mechanically changing the rods.

  • the kinetic energy conversion device is configured such that one end of the rod can be received. At least one wall of the kinetic energy conversion device is conically tapered to an opposite wall. Upon impact of a vehicle with the impactor, the kinetic energy conversion device is then further pushed onto the respective rod in the direction of the longitudinal axis of the rod, the rod then being compressed in the region of the conical wall, thereby transferring kinetic energy into the deformation of the rod.
  • the rods are arranged parallel to each other.
  • the kinetic energy conversion device encloses the rod. This measure prevents the pole can break out to one side.
  • the kinetic energy conversion device has on one side, which is arranged in particular transversely to the longitudinal axis of the rod, an opening through which the mechanically changed rod can pass or pass. This prevents that the mechanically modified rod can injure persons in approaching vehicles.
  • the rod preferably has a rectangular, in particular preferably a square cross section.
  • the kinetic energy conversion device surrounding the rod accordingly preferably also has a rectangular shape or, in particular, preferably a square shape.
  • a sliding sleeve for example of a plastic material, is provided at the entrance area of the kinetic energy conversion device.

  • the hinge is also designed to be sheared by the kinetic energy conversion device.
  • the hinge is arranged to move relative to the respective one upon movement of the kinetic energy conversion device Rod comes into the effective range of the hinge, so that it is sheared off.
  • the fold-up part of the impact damping device is very efficient and easy to fold up if at least one hydraulic cylinder, in particular one hydraulic cylinder attached to the outer rods, is provided for moving the foldable part of the impact damping device.
  • At least one hydraulic synchronizing cylinder serves for fixing the foldable part of the impact damping device.
  • This can compensate or withstand very high forces, which can occur in particular during transport from a folded-up impact damping device.
  • the one or more hydraulic synchronizing cylinders are designed so that they can be extended or compressed with open valve, without much effort, so that the hydraulic synchronizing cylinder, the movement of the hydraulic cylinders, which are provided as actuators to fold up the hinged part of the impact damping device or shut down, join in.
  • the valve is closed, whereby the length of the expansion cylinder or the same does not change and without the hydraulic cylinder must continue to be operated, the foldable part of the impact damping remains folded.

  • a curved wall 32 is shown, which serves to deflect the squeezed rod 12 in one direction, so that the mechanically modified rod does not reach the area of the approaching vehicle, so that no person can be injured by the mechanically modified rod 12 ,
  • the mechanically modified rod 12 is derived downward or to one side.
  • FIG. 2 is still a shearing plate 30 shown, which serves, for example, the underride guard 20 and the wheel housing 22 and the wheel axle 21 to shear, if a vehicle ascends on the impact plate 13.
